To reduce the effects of electromagnetic disturbance, keep the sensor and signal cables wellseparate from the power wires. -
Place the probe T1 inside the room in a point that truly represents the temperature of the stored product.
-
Place the probe T2 on the evaporator where there is the maximum formation of frost.
-
The function of probe T3 is determined by the parameter T3.
DISPLAY INFO
In case of alarm, press any key to mute the buzzer sound.
OPERATION
SETTING
DEFROST START
DEFROST TERMINATION
Resuming thermostatic cycle. When defrost is over, if DRN is greater than 0,
all outputs will remain off for DRN minutes, in order for the ice to melt
completely and the resulting water to drain. Then, after the FTO time has
elapsed, the evaporator fans will restart. Differently, if T2=YES and this
probe measures the FDD temperature before FTO elapses, then the fans re-start
immediately.
Caution: if DFM=NON all defrost functions are inhibited; if DFT=0, automatic
defrost functions are excluded. During defrost, high temperature alarm is
bypassed.
CONFIGURATION PARAMETERS
FIRST CONFIGURATION
At the first power-up, “SEt” is displayed, to indicate that the controller
needs a first configuration.
Tap , PS will be displayed. Once again tap , then select the profile desired
among the options available via or . After selecting the option of choice, tap
again. The display will now show SCL (readout scale). If need be, by tapping ,
